Abstract: Conversion of used sunflower oil was carried out thermal and in the presence of different catalysts (Na2 CO3, silica- alumina, and HZSM- 5) in a reactor (#316 SS tubing, 210 mm long, 45mm i.d.) equipped with thermocouples, inert gas connection and packed fractionating column (#316 SS tubing, 540mm, 45mm i.d., packed with ceramic rings having 7mm i.d.). The products consisted of gaseous and liquid hydrocarbons, carboxylic acids, CO, CO2, H2, water, coke, and residual oil. Highest conversion of oil (73.2%) and the maximum amount of the liquid hydrocarbon product (32.8%) were obtained at 420 °C with Na2 CO3 as catalyst. The liquid hydrocarbon products consisted mainly of hydrocarbons in the gasoline boiling range.
